Question

Jonny is writing a program for a video game. For one part of the game he uses the rule given bellow to move objects on the screen. Give the output that the rule gives for the inputs. (X,y)

Answer 1

Assume the input is $I=(a;b)$, and the rule is $(x+x_1; y+y_1)$, where x and y are the input values, x₁ and y₁ are constants that define the rule. Then the output for our input will be

$$O=(a+x_1;b+y_1).$$
